Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...e same, however. Parasites in different geographic regions have developed unique patterns of mutations in the three genes mentioned above. Now, researchers can tell where a drug resistant parasite comes from depending on the varied mutations in the three different resistance genes, Roepe said. "There are pat...

Largest ever study of genetics of common diseases published today

... most significant new findings are four chromosome regions containing genes that can predispose to type 1 diabetes and three new genes for Crohn's disease (a type of inflammatory bowel disease). For the first time, the researchers have found a gene linking these two autoimmune diseases, known as PTPN2. The...

Using a new technique to switch off neural activity in selective brain cells in living mice, Gross and his colleagues discovered that a specific part of the...

Cigarette smoke alters DNA in sperm, genetic damage could pass to offspring

Focal adhesions are regions rich with receptors for growth factors and they are also structural attachment points that link the extracellular world to the protein filaments and tubes that comprise a cells internal cytoskeleton.

It is sporadic and happens over a small area for a limited amount of time." In some areas of the world, such as the equator, there are no cyclone...

Want to save polar bears? Follow the ice

Bears that make it to shore may be there for increasingly longer periods of time without food as the sea ice becomes more distant and inaccessible. The main question for conservationists is wh...

Specific regions of interest were selected from EUS images of patients with normal pancreas readings (group one, n=110), established CP (group two, n=99), or confirmed PC (group three, n=110) and analyzed using DIA. The team performed a variety of digital image anal...
